Grateful for all advice. Our property is 12 years old. My wife is getting agitated about a strange smell in our en-suite bathroom near to our close fitted toilet bowl. There are no leaks. I have checked the traps on the bath, bidet, shower and wash-basin. They all seem fine. The soil pipe is internal with an AAV in the eaves. I haven't been up to check this as I am probably a bit too old for climbing into lofts. I have removed the drain cover and waste water is flowing. There are no strangle gurgles when the toilet is flushed or bath etc emptied.
The only work that has been carried out in the past few months is a replacement toilet bowl - the original one wasn't glazed properly and it became discoloured in use. I do not know whether the plumber used a new push in connector. I am clutching at straws here but is it possible for the connector to leak air but not leak water. I am thinking perhaps of a small leak/gap on the upper surface or the connector/soil pipe.
Anything else I should check?
